Customize virtual serial port while cloning from template VM

Hey Folks,

I have a template VM that has a serial interface. Part of the template vmx file looks like below,

serial0.fileType = "network"

serial0.fileName = "telnet://xxx.xxx.xxx.xxx:63001"

serial0.yieldOnMsrRead = "TRUE"

serial0.present = "TRUE"

I would like to clone VMs using this template but every new clone should use a new port in the serial0.filename. I went through most of the documentation, but did not see if this can be done through the customization. Does the perl sdk (vmclone.pl) allows this?

Thanks in advance.
